摘　　要：该文对青草沙水库2013年1月-2015年12月三年间叶绿素a含量和藻类生物量进行了时间和空间上的调查研究。结果表明，青草沙2013年-2015年运营期浮游植物生物量基本保持稳定，叶绿素a含量和藻类生物量呈显著正相关。在冬春或冬末春初、夏末秋初季节交替时节容易形成藻类密度高峰，春季藻类密度和生物量均高于其他季节。样点上游闸外叶绿素a与藻类密度最低，库中最高。Temporal and spatial investigation and analysis of chlorophyll-a content and algal biomass in the three years of Jan. 2013- Dec. 2015 in Qingcaosha Reservoir were made. Results show that biomass of phytoplankton remains stable during the 2013-2015 operation period, and chlorophyll-a content is significantly positively correlated with the biomass of algae. In the winter or late winter to early spring, late summer to early autumn, it seems to form the peak density. Besides, spring algal density and biomass are higher than other seasons. Chlorophyll-a and algal density in the upper reaches of the sample point is the lowest and the highest in the middle of reservoir.
